Definition
Off road tracking dots that can be followed on the map to retrace your route back to a
mapped (digitized) road. This function can be turned on/off in Setup screen 1.
Central Processing Unit. The main device within the navigation unit that coordinates the
rest of the electronic functions.
This consists of the Map data, and the POI (Points Of Interest) data stored on the DVD.
Detailed Coverage Area. Main metropolitan areas in the Lower 48 states, and Canada are
mapped to this level. See the Navigation Owner's manual for a list of these areas.
Diagnostic Trouble Codes. Use the HDS tablet to obtain, and troubleshoot the cause of
these codes.
The use of the speed signal, and yaw rate sensor to position the vehicle on the map even
when the GPS signal is obscured by tall buildings, or while driving in a tunnel.
A road that appears on the navigation screen. The road name will appear at the bottom of
the navigation screen. If the user drives "off road" the navigation system will display
"Not on a digitized road", and if 1/2 mile, then "breadcrumbs" will appear.
Screen containing cautionary information. It is meant to read carefully and acknowledged
by the customer when using the navigation system.
Digital Versatile Disk. The navigation program and database resides on this disk. See the
Navigation Owner's Manual for information on how to order a replacement or update
DVD.
Engine Control Module. Typically referred to as the PCM
Frequency Asked Question. See the Navigation Owner's Manual for a list of the customer
FAQs, and troubleshooting information
Proprietary communication bus. This serial bus connects the audio unit, navigation unit,
display unit, and XM receiver. Signals passed on this bus include audio muting requests,
navigation and display unit buttons, control commands, and XM control sequences.
Global Positioning System. A network of 24 satellites in orbit around the earth. The navi-
gation system can simultaneously receive signals from up to 12 satellites to accurately
positioning the vehicle on the map.
Honda Diagnostic System. A hand held tablet PC for use in diagnosing vehicle problems.
This device can be used to obtain DTC codes for diagnosis of navigation system CAN
related problems.
Head Unit. The navigation system display unit assembly in the dash.
This refers to the period needed to re-acquire the GPS satellite orbital information when-
ever the navigation system power has been disconnected. This can take from 10 to 45
minutes.
Liquid Crystal Display (the navigation screen)
The received GPS information allows the navigation system to position the vehicle on the
map. Map matching has occurred if the map screen is displaying the current street name
in the bottom-shaded area.
Abbreviation for the microphone used for receiving voice commands. It is located near
the map light in the ceiling
